Electronically controllable pneumatic braking system for commercial vehicle and electronic control method of pneumatic braking system for commercial vehicle

摘要

The present invention relates toWith respect to the electronically controllable pneumatic braking system of vehicleAt leastBrake wheel234 andBrake control pressure paA foot brake valve 11 for providing Pb by pneumatic pressureThe foot brake valve 11 is provided with a bypass valve configuration 16 for providing a foot brake input pressure p.sub.e which serves as an electronic air pressure type.These wheel brakes234Axle modulator 9By 10Brake control pressure paNormal brake brake pressure P1 corresponding to PbP2,P3It is possible to give P4;Brake control pressure paPBBy foot brake valveIt can be generated in accordance with mechanical or electronic air pressureBypass valve configurationFor foot brake valveElectronic air pressureA low pressure level is provided at the first switching positionThe second switching position Z2 gives a high pressure level.The foot brake input pressure p.sub.e given by the bypass valve configuration 16 as the electron air pressure imparting can be passed through the exhaust space and the operating space of the foot brake valve 11 as normal brake control pressures PA and .
